Description: This function separates the surfaces of a solid geometry into upper and lower surfaces, and places them in new parts.
Usage:
1. DSI prompts:
> SELECT SURFACE
2. After selecting surfaces, DSI prompts:
• ADD TOP SURFACES: add bottom surfaces to top surfaces
• REMOVE TOP SURFACES: remove top surfaces to original surfaces.
• TURN OFF OTHER PARTS: don¡¯t display parts except part including top surfaces.
• GROUP BOTTOM SURFACES: turn to bottom surfaces operation.
3. After generating top surface group, DSI prompts:
• ADD BOTTOM SURFACES: add other surfaces to bottom surfaces.
• REMOVE BOTTOM SURFACES: remove bottom surfaces to original surfaces.
• TURN OFF OTHER PARTS: don¡¯t display parts except part including bottom surfaces.
• DONE: finish and exit this function.
